Now it's well past the point of painting outdoors with dew and the beginning of frost nights and such, so I'm wondering, how does the paneling (fine-sawn standing) fare if you nail it up untreated and leave it until the weather gets more pleasant, maybe in May?
Does it help at all if you apply primer oil? (I have two buckets that were never used when we changed the facade on the house.)

As an amateur, I think it should work well. I have a gavel peak that's soon starting its 3rd winter, and I don't think it has taken any damage. I paint when I have time.
Clearly better with oil than without...
What can/will happen is that you get grey wood and/or mold on the boards, but you brush and wash that off before painting.
Slightly better is to oil and apply a base coat once.
A little dew on the base coat doesn't matter - it's the top coat you don't want moisture on.
Just look at how many Älvsby-hus, Myresjö-hus, etc., are standing with delivery base coats over the winters...

Panel that gets the chance to dry now and then lasts a long time, it's not a problem. I have a storage shed left to build before winter, was planning to paint that panel if there's just a little sun in October, don't think it matters much with stain on a cold storage, it can breathe out the moisture inward if nothing else. But otherwise, I'll do like other Uppsala residents (Amateur builder) 
paint when I have time.
paint when I have time.So I smack it up and spread the base oil I have then. Not sure if it might have gone rancid, it's a bit cloudy, but maybe that doesn't matter too much?
I'm painting panels full time for our house. I lay each panel board with spacers and cover it overnight with a tarp. It's better to finish-coat once than to nail up unpainted ones, since the risk is ending up with a striped house when the wood has dried after painting on site.
If I paint all the paneling on the ground, I'll probably be at it until December; there are over 200 boards. I know there's a risk of streaks, but right now I just need to get the "crap" off the ground and protect the garage wall, so I'll deal with it then if needed. If it's also unpainted on the wall and dries, it should reasonably shrink on its own if it's over half a year until it's time to paint, right?
If it's lockpanel you're going to install, it's not ideal to paint them after they're on the wall. They will shrink a bit over time, and unpainted wood will show through the joints, which is a hassle to paint over again.
In half an hour, you'll probably paint 20 boards.cheetah1 said:
Devote an hour a day, and it's done in a week.
Look at it positively: Once it's painted, you won't have to redo it for at least ten years.

In half an hour, I paint 8 boards, which then need to dry for 24 hours before being painted again, and then dry for 24 hours before my limited painting space is available again.
In other words, it doesn't take a week but two months.

We are also painting in a limited space.
Solved it by standing the boards on edge.
Place two 45x95 studs straight out from the wall with support at the outer ends.
The studs are set at a comfortable working height.
On the studs, nail 40 4" nails with 30 mm spacing. Just enough for the painted boards to fit on edge between the nails. Our boards are 200mm wide, so we can fit 40 boards instead of 7.
To move the newly painted boards, make two holders out of 45x95. A few centimeters longer than the width of the board. Hammer in 2 nails with spacing about 5 mm longer than the width of the board. Hammer them in so they stick out a few mm more than the thickness of the board. Now just place the holders over the board with the nail heads down past the edge of the board. Angle the holders outward on the topside and it’s easy to move the boards without getting paint on yourself.
Hope I've explained it reasonably well!

Jan-Å is right, leave the painting until spring. The panels have time to dry, and you can paint with less risk of shrinkage afterwards. The important thing, as with all painting, is to saturate the end grain with wood oil as the first step of painting in the spring.
I painted my garage panel when it was mounted, the neighbor folks grumbled because you're supposed to paint before mounting to avoid stripes, etc. I completely agree with cheetah1, it takes too long to fiddle like that, months compared to a week. Sure, it has shrunk a bit here and there but not worse than it could be painted on those boards in half an hour. What shrinks in the spring I'll spend half an hour on then.
